In 2014, the Superfund Program implemented a new information system, the Superfund Enterprise Management System (SEMS).
Efforts to migrate data to SEMS and to enhance data quality control are now in the final stages.
The Program will continue to rely on the final CERCLIS data set (dated November 12, 2013,
which reflects official end of Fiscal Year 2013 Program progress) for public reporting until a complete and accurate SEMS data set is available.
The current estimate for refreshing the content on this page is April 2015.

The chemical substances (i.e., hazardous substances, pollutants, or contaminants)
listed below were identified as contaminants of concern (COC) for the site. COCs
are the chemical substances found at the site that the EPA has determined pose an
unacceptable risk to human health or the environment. These are the substances that are
addressed by cleanup actions at the site. Identifying COCs is a process where the
EPA identifies people and ecological resources that could be exposed to contamination
found at the site, determines the amount and type of contaminants present, and identifies
the possible negative human health or ecological effects that could result from contact
with the contaminants.

Chemical Abstracts Service (CAS) is a division of the American Chemical Society. CAS
builds and maintains the largest and most current database of chemical substance
information in the world. These chemical substances are labeled with CAS Registry
Numbers® (CASRNs or CAS Numbers) and are used internationally as unique numeric
identifiers for a single substance. They have no chemical significance and, because
they are widely used, are a link to a wealth of information about a specific chemical
substance. They are provided here for reference purposes to hopefully aide you in
researching the respective chemical. For more information,
visit the CAS Web site.

About ATSDR

The Agency for Toxic Substances and Disease Registry (ATSDR) is an agency of the U.S. Department of
Health and Human Services. ATSDR is charged under the Superfund law (CERCLA) to assess the presence
and nature of health hazards at specific Superfund sites, to help prevent or reduce further exposure
and the illnesses that result from such exposures, and to expand the knowledge base about health
effects from exposure to hazardous substances. ATSDR maintains a series of fact sheets and profiles
about contaminants of concern commonly found at Superfund sites. Links to these resources are
provided above when available. For more information,
visit the ATSDR Web site.

About EPA’s IRIS

The Integrated Risk Information System (IRIS), prepared and maintained by the U.S.
Environmental Protection Agency (U.S. EPA), is an electronic database containing
information on human health effects that may result from exposure to various chemicals
in the environment. IRIS was initially developed for EPA staff in response to a growing
demand for consistent information on chemical substances for use in risk assessments,
decision-making and regulatory activities. The information in IRIS is intended for those
without extensive training in toxicology, but with some knowledge of health sciences. For
more information, visit the EPA IRIS Web site.

About EPA’s SRS

The Substance Registry System (SRS) is the Environmental Protection Agency's (EPA) central
system for information about regulated and monitored substances. The system provides a common
basis for identification of chemicals, biological organisms, and other substances listed in
EPA regulations and data systems, as well as substances of interest from other sources,
such as publications. The system does not provide health hazard information at this time. For
more information, visit the EPA SRS Web site.
